The global mega-star was pictured wearing the Toffees third strip while he played in a football tournament on an island in Turks and Caicos on Friday.

Bieber, 20, who has been named as one of the top 10 most powerful celebrities in the world and has more than 58 million Twitter followers, is believed to have been staying on the island which is owned by Everton director Robert Earl.

Planet Hollywood founder Earl is an influential figure in stateside show business, and staged the tournament on his private Parrot Cay resort island, where Bieber and pals wore Everton's 2014/15 season white and purple third kit.

As photographs of the Goodison outfit's remarkable new supporter emerged on Twitter, they quickly went viral with Evertonians posting a series of photshopped pictures incorporating their unlikely fan.

But while Bluenoses saw the funny side, Roberto Martinez may not be too impressed.

US sports-fans were quick to warn their Scouse counterparts that whenever Bieber supports an American team, their fortunes swiftly plummet.
